Armstrong insulators are a favorite among collectors for their quality American production and strong clarity. The DP-1 is a clean, classic form and this example is exceptional — no haze, no damage, strong glass integrity. Crystal clear insulators are particularly versatile for display, as they catch and scatter light beautifully. Great as a windowsill piece, shelf display, or addition to a larger insulator collection.
One-of-a-kind piece. Once sold, it is gone. Only one available. Questions welcome before purchase.
